Mechanistic Insights into Cu‐Catalyzed Asymmetric Aldol Reactions: Chemical and Spectroscopic Evidence for a Metalloenolate Intermediate
摘要:
In situ IR spectroscopy and transmetalation experiments confirm a postulated catalytic cycle. The metalloenolate 1 describes the active intermediate in the aldol reaction catalyzed by [CuF2{(S)-tol-binap}] (see reaction scheme). (S)-tol-binap=(S)-(-)-2,2-bis(di-p-tolylphosphanyl)-1,1-binaphthyl.
